MACHINE FOR WINDING YARN INTO COPS.

SPECIFICATION forming part of Letters Patent No. 458,927, datedSeptember 1, 1891.

Application filed June 24, 1890. Serial No. 856,728. (No model.)Patented in England September 12, 1887, No. 12,331, and

September 26,1888, No. 13,863.

To [tZZ whom it may concern.-

Be it known that I, JOHN DEMPsTER WVHYTEpf Manchester, England, haveinvented a new and Improved Machine for \Vinding Yarn into Oops, (forwhich Letters Patent of Great Britain Nos. 12,331 and 13,863, datedSeptember 12, 1887, and September 26, .1888, respectively, were grantedto me,) of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved machine forwinding yarn into cop form on bare spindles without pirns, spools, ortubes, such as yarn is commonly wound on, and also without cups, such asyarn is commonly wound in, to avoid all frictional contact with theyarn.

The invention consists of certain parts and details and combinations ofthe same, as will be hereinafterfully described, and then pointed in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improvement. Fig. 2 is a transversesection of the same, and Fig. 3 is a sectional plan view of part of theimprovement.

The improved yarn winding machine is provided with asuitably-constructed frame A, carrying at the front and rear the siderails B B. The vertically-arranged spindles O are mounted to turn insuitable bearings in a frame H, which is mounted to swing in suitablebearings in the rails 13 and B, of which the latter are locatedlongitudinally near the middle of the frame. On the lower end of eachspindle U is fixed a beveled friction- Wheel 0, which receives itsrotary motion from frictional contact with a beveled wheel O on thedriving-shaft E, which is set in motion in any suitable manner fromproper machinery.

On each of the spindles is secured a small pulley F, over which passes abelt or cord F, extending inward and passing over a larger pulley Fsecured on the lower end of a shaft G, arranged vertically and mountedto turn in suitable hearings in the frame II.

The shaft G is rotated from its respective spindle O, and on it is heldto turn and to slide a cam I, preferably made in the shape of a disk setat an angle on the said shaft, as is plainly shown in Figs. 1 and '2.The vertical movement of the cam I is accomplished by an arm J, engagingthe hub of the said disk and secured on a half-nut J, en-

gaging a screw-shaft K, mounted to turn in suitable bearings in theframe H, and carrying at its lower end a wheel K, engaging the face of alarge wheel L, secured on a shaft L, mounted to turn in suitablehearings in the ends of the main frame A, and rotated in any suitablemanner. The wheel K can be vertically adjusted by a set-screw or otherdevice, as shown in Fig. 1, on the lower end of the screw-rod K, so asto hold said wheel in contact with the face of the wheel L farther fromor nearer to the shaft L, so that when the latter is rotated the wheel Kis rotated with more or less speed, according to its distance from thetransverse center of the shaft L.

On the half-nut J is mounted a pivot J engaging a vertically-arrangedslotted guide J held on the frame H. This pivot J and its guide J 3 holdthe halfnut J on the shaft K, and the arm J prevents the half-nut K fromturning, so that when the shaft K is rotated, as above described, thesaid half-nut moves up or down on the screw-rod K.

On the pivot J 2 is secured an arm N, formed at its outer end witha forkwhich engages the cam-Wheel I, so that when the latter rotates anoscillating motion is imparted to the said arm N. On the pivoted end ofthe latter is secured the thread-guide O, provided on its free end withthe usual eye 0, through which passes the thread P onto the cop D. Thethread P, before it passes into the eye 0, passes over alongitudinally-arranged rod P, having previously passed through the eyeQ, after unwinding from the usual swift. The eye Q, above mentioned, isformed on a lever Q, f ulcrumed on one arm of a bell-crank lever B, theother arm of which lever is adapted to withdraw a block S, against whichrests the upper end of the frame H. The bell-crank lever B is fulcrumedat R to a standard R on the longitudinally-extending rail R secured tothe ends of the main frame A. The

lever Q is counterbalanced, and is provided with a downwardly-extendingprojection Q adapted to engage,when the thread P breaks, with one of aseries of lugs T, formed on a shaft T, extending longitudinally andmounted to rotate in suitable bearings on the main frame A. It will beseen that when the thread P breaks the lever Q drops downward, so thatits projection Q is engaged by one of the lugs T on the shaft '1, theeffect of which is to draw the lever Q outward, so that the bell-cranklever B is actuated and moves the block S upward to permit the frame Hto fall into an inclined position, as illustrated to the right inFig. 1. The frame H oscillates on its fulcru ms H, so that the wheel Kis thrown out of frictional contact with the large wheel L, and themotion of the shaft K ceases, and similarly the wheel 0 on the lower endof the spindle O is thrown out of frictional contact with the wheel 0and the motion of the spindle O ceases. As the shaft G derives itsrotary motion from the spindle C, it will be seen that the falling ofthe frame H into an inclined position, as above described, causes themotions of the spindle O, the shaft G, and the screw-rod K to ceasesimultaneously. \Vhen the operator has mended the broken thread, themovem ent of the block S intoposition again behind the frame H causesthe operation of winding to proceed as before. From the block S extendsdownward an arm S, adapted to be engaged by the arm J to move the saidblock S away from the upper free end of the frame H to permit the latterto swing into an inclined position to stop the motion of the spindle O,the shaft G, and

the screw-rod K, as previously described in.

reference to the breaking of the thread P. This movement takes placewhen the cop is formed-that is, when the half-nut J is in its uppermostposition on the screw-rod K. In order that the beginning of the cop maynot be tapering or conical, as at the close of the cop, but may have athick instead of a tapered beginning, the traversing movement is shorterat the beginning than after desired thickness of the cop has been builtup. The slotted guide-rod J which holds the halfhut J on the screw-rod Kis at its lower end slightly curved toward the spindle, as is plainlyshown in Fig. 2. The pivot J upon which the arm N is swiveled, is freeto slide up or down in the slot of the guide J The pivot being securedon the half-nut J, so as to slide backward or forward, is nearer to thespindle C, while it is in the curved lower end of the guide J As thehalf-nut J is slowly carried upward, the pivot gradually recedes fromthe spindle until the pivot, havin g passed the curved part of the guideJ is now in the vertical straight part of the latter. Thus while thepivot is nearer to the spindle when near the bottom of the guide J 3 theforked ends of the arm N, in contact with the cam I, are farther fromthe edge of the cam I, and thereby give the thread-guide 0 a shortthrow, which short throw gives a corresponding short traverse in thelaying on of the yarn upon the spindle 0. As the curved part of theguide J 3 makes the pivot to gradually recede from the spindle, so theforked ends of the arm. N upon the sides of the cam I gradually approachthe edge of the said cam, and thereby the throw of the threadguide 0 andthe corresponding traverse in the laying on of the yarn upon the spindlebecome gradually longer until the pivot has begun to travel along thestraight part of the guide J and the throw of the thread-guide and thelength of the traverse will then con tinue unaltered until the cop isfinished and the thread-guide and the cam are lowered to begin a newcop. It will be understood that the onward movement of the half-nut J sofar counteracts the lengtheningof the traverse that the thread will notbe traversed beyond the beginning of the cop, but all the length eningof the traverse will go in the direction of the point of the spindle,thereby forming a thick instead of tapered beginning for the cop. It isunderstood that when the spindle '0, the shaft G, and the screw-rod Kare in motion the revolution of the cam I imparts the necessarytraversing motion to the threadguide 0, so that the latter places thethread or yarn P upon the spindle, while the upward motion of the cam onthe shaft G is properly building the yarn into the cop form. Inasmuch asa quicker or slower progress in that onward motion of the cam I Willbuild yarns of the uniform thickness into a smaller or thicker cop form,and as for fine yarn a slower progress and for coarser yarns a quickerprogress in that onward motion of the cam is necessary, an easy methodof altering that rate of progress is obtained, so that cops may be builtsmaller or thicker, as may bedesired, so that different kinds ofthicknessesof yarns may be built into uniform thicknessesof cops. Thisis done by changing the wheel K on the screw-rod K, as previouslydescribed, to impart a faster or slower motion to the screwshaft. Whenthe cop is formed to the requisite length, the arm J, of the half-nut Jengages the arm S of the block S, so that the latter is moved out of itsplace and the frame H swings into an inclined position to stop themotion of the spindle O, the shaft G, and the screw-shaft K, aspreviously described. The operator then lifts the half-nut from thescrewrod K and allows the half-nut and the cam I to fall or to be moveddown into their lowermost position to such part of the shaft G andscrew-rod K as gives the desired beginning of the formation of the cop.

It will be understood that while I have de scribed and indicated avertical arrangement of the spindles and their parallel shafts saidspindles and their parallel shafts may be arranged in an oblique orhorizontal position, provided the necessary alterations in theapplication of the driving and stop motions are made. Further, that anysuch number of IOC spindles as is .desired may be arranged in the lengthof the machine, each one having its accompanying traversing motion, and,further, that While only one thread is represented as being wound intoeach cop in Figs. 1 and 2 two or more threads may be wound at the sametime, in which case drop-wires for each thread may be arranged.

I do not limit myself to the precise construction of the various partsshown and described, as the same may be varied to accomplish the sameresult or may be adapted to other machines.

Having thus fully described my invention, I claim as new and desire tosecure by Let-- ters Patent- 1.
